Quality Control

Our Flavone Ii is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods, to ensure it meets the high standards required for research and development. A detailed Certificate of Analysis (COA) is provided with each shipment, documenting batch-specific results.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its light-sensitive and easily oxidized nature, prolonged exposure to light and air should be avoided. For long-term storage, consider an inert atmosphere.
